Answer 1

An eraser is an article of stationery that is used for removing pencil markings. Erasers have a rubbery consistency and are often pink or white. Some pencils have an eraser on one end. Typical erasers are made from synthetic rubber, but more expensive or specialized erasers are vinyl, plastic, or gum-like materials. Cheaper erasers can be made out of syntheticsoy-based gum.
